CVE-2025-30449: 
macOS vulnerability analysis and mitigation

A permissions issue was discovered in macOS that allows an app to gain root privileges. The vulnerability (CVE-2025-30449) affects multiple versions of macOS including Ventura 13.7.5, Sequoia 15.4, and Sonoma 14.7.5. The issue was disclosed on March 31, 2025 and was addressed by Apple with additional restrictions in security updates released for the affected operating systems (Apple Advisory, Apple Advisory, Apple Advisory).

The vulnerability exists in the StorageKit component of macOS and is classified as a permissions issue (CWE-281: Improper Preservation of Permissions). The vulnerability has a CVSS v3.1 base score of 7.8 (HIGH) with the following vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This indicates that the vulnerability requires local access and user interaction to exploit, but can result in high impacts to confidentiality, integrity, and availability (NIST NVD).

If exploited, this vulnerability allows a malicious application to gain root privileges on the affected system. This level of access would give an attacker complete control over the system, potentially allowing them to access protected files, modify system settings, and execute arbitrary code with the highest privileges (Apple Advisory).

Apple has addressed this vulnerability by implementing additional restrictions in the StorageKit component. Users are advised to update to macOS Ventura 13.7.5, macOS Sequoia 15.4, or macOS Sonoma 14.7.5, depending on their operating system version. These updates contain the necessary fixes to prevent exploitation of this vulnerability (Apple Advisory, Apple Advisory, Apple Advisory).

The vulnerability was discovered and reported by security researcher Arsenii Kostromin (0x3c3e) along with an anonymous researcher. The discovery highlights ongoing security research efforts in identifying privilege escalation vulnerabilities in macOS systems (Apple Advisory).
